Isotonic

** Isotonic solution, hypotonic solution, hypertonic solution **

isotonic solution：等張溶液，與A溶液的溶質濃度相等的B溶液，稱為A溶液的等張溶液

ex. isotonic solution is one that has the same solute concentration as compared to another

isosmotic solution：等滲溶液，與A溶液的滲透壓相等的B溶液，稱為A溶液的等滲溶液

ex. isosmotic solution is one that has the same osmotic (water) pressure as compared to another

hypertonic solution：高張溶液，比A溶液的溶質濃度高的B溶液，稱為A溶液的等滲溶液

ex. 當細胞的水勢比細胞外的液體高時，細胞水分子往外滲透

hyperosmotic solution：高滲溶液，比A溶液的滲透壓高的B溶液，稱為A溶液的等滲溶液

hypotonic solutio：低張溶液，比A溶液的溶質濃度低的B溶液，稱為A溶液的低張溶液

hypoosmotic solution：低滲溶液，比A溶液的滲透壓低的B溶液，稱為A溶液的低滲溶液
